Questions about AS17621
Is AS17621 a VPN or hosting network?
Fraudex does not list AS17621 (CNCGROUP-SH) as a VPN, proxy or hosting network. Its addresses are treated as regular traffic, apart from any Tor exit relays.
Which country is AS17621 registered in?
AS17621 is registered in China. Individual addresses can be used elsewhere, so check the IP itself when location matters.
How many IP addresses does AS17621 have?
It announces 176 IPv4 ranges with 888,064 addresses in total, plus 160 IPv6 ranges.
How do I block traffic from AS17621?
Blocking a whole network by number goes stale as ranges change hands. It is more reliable to check each visitor's IP when they sign up, log in or pay: the Fraudex API returns the network and a VPN and bot verdict, so you can block, challenge or just log flagged traffic. See why an IP blocking API pays for itself.
